According to initial reports, the small-arms attack came primarily from an unoccupied four-story building to the south of the barracks. Insurgents fired two rockets from the area to the west of the Helmand River known as the Bolan Desert at about 10 a.m., and the rockets are believed to have landed west of the barracks.

This coordinated attempt by insurgents to launch an attack continues, officials said, but is being contained by Afghan forces. The main group of attackers was pinned down in a vacant building south of Sharwali Barracks. Attack helicopters are over the city and have fired upon insurgents.

No casualties have been reported.
